My mate's been quite ill. Recently, she got an old and quite skanky chandelier of off Craig's List. According to it's original documentation, it's all hand-cut leaded crystal (under a thick encrustation of dust and nicotine). We spent the whole evening working together disassembling and cleaning it (it reeked of at least 50 years of cigarette smoke ;P ). She'd periodically go into the living room, hold up a freshly cleaned bauble to the light, and squee delightedly when it cast little rainbows all over the room. I can't even begin to express what it's like to see her so engaged and happy.
